Summary

Path traversal vulnerability in BlenderMCP before commit 30a3308 in the download_polyhaven_asset method. Attackers can inject '../' sequences in API response include keys, allowing arbitrary file overwrite.

Risk Assessment

An attacker can overwrite sensitive files like .bashrc, leading to persistent code execution and system compromise.

Recommendation

Update BlenderMCP to the fixed version (commit 30a3308) and implement path validation in the download_polyhaven_asset method.

Original NVD description (English source)

BlenderMCP before commit 30a3308 contains a path traversal vulnerability in the download_polyhaven_asset method that allows attackers to write arbitrary files by injecting traversal sequences in API response include keys. Attackers performing MITM attacks or prompt injection can supply malicious paths like '../../.bashrc' to overwrite sensitive files and achieve persistent code execution.
